Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment for liquid attitude control engine systems, and more specifically to a packaging box for transporting liquid attitude control engine systems carrying propellant. Background Technology

[0002] Liquid attitude control engine systems provide power for spacecraft orbital transfers and attitude adjustments. The propellant used in these systems is a flammable, explosive, and highly toxic substance. Propellant leakage during transportation, storage, refueling, and testing can directly endanger the health and safety of operators and related personnel, causing equipment damage and environmental hazards. Therefore, the reliability of the packaging for liquid attitude control engine systems transported with propellant, as well as the monitoring and measurement of propellant leakage concentrations during transport, are extremely important.

[0003] Currently, the transportation of liquid attitude control engine systems does not include propellant. Since propellant is a toxic and harmful substance, there are certain requirements for the refueling site. For tests where the test site does not have the conditions for refueling, propellant needs to be refueled first before transporting the system from the refueling site to the test base. During transportation, the liquid attitude control engine system needs to be installed in a stable and reliable packaging box, and the system must be able to detect whether propellant leakage occurs during transportation to avoid danger. Summary of the Invention

[0004] To address at least one deficiency in the prior art, this invention provides a packaging box for transporting a liquid attitude control engine system carrying propellant. This packaging box can stably and reliably fix the liquid attitude control engine system on a mounting frame, effectively preventing collisions and structural deformation of the individual units within the liquid attitude control engine system. The packaging box has a three-layer structure, with an internal propellant concentration detector capable of real-time monitoring for propellant leakage. An exhaust fan is installed on the side of the packaging box, with a hose at the exhaust fan to deliver air from inside the packaging box to a water tank containing deionized water, which can effectively treat leaked propellant to prevent danger.

[0005] The technical solution adopted in this invention is a packaging box for transporting a liquid attitude control engine system carrying propellant, comprising an upper box, a middle box, and a lower box from top to bottom. The middle box includes a latch and a filter screen. The lower box includes a flange, an exhaust fan, bolts, a switch, a handle, a latch, and a grounding post. The middle box is connected to the lower box via the latch. The middle box is connected to the upper box via a hinge and then locked to the upper box via the latch. A concentration detector and a concentration monitoring device shelf are welded to the side of the middle box. The filter screen is installed on the side of the middle box. The lower box is connected to the middle box via the latch and a fixed bracket is connected to the lower box via bolts. An exhaust fan is provided on the side of the lower box. A flexible hose is provided on the outside of the exhaust fan. The flexible hose is connected to the outside of the lower box via a flange and is inserted into a water tank.

[0006] The filter screen and the exhaust fan are positioned diagonally opposite each other.

[0007] The filter screen has a mesh size of 80.

[0008] The exhaust fan is controlled by a switch.

[0009] The bottom of the lower housing is equipped with a grounding post to prevent static electricity.

[0010] The lower part of the fixed bracket is fixed to the lower box body through a U-shaped hole, and the upper part of the fixed bracket is connected to the product through a U-shaped hole.

[0011] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a simple structure, is stable and reliable, and has strong adjustability and versatility; it can detect the propellant concentration in real time to determine whether a propellant leak has occurred, so as to deal with it; an exhaust fan is installed on one side of the packaging box, and a hose at the exhaust fan can transport the leaked propellant to the water tank, which is filled with deionized water, so as to effectively treat the leaked propellant and prevent danger; the packaging box can suspend the engine nozzle, and the liquid attitude control engine system can be reliably fixed in the packaging box to prevent collision; the fixing bracket is provided with a U-shaped hole, and the position of the fixing bracket can be adjusted for the transportation of different models of liquid attitude control engine systems.

The middle box 2 includes a central locking buckle 21 and a filter screen 22. The lower box 3 includes a flange 31, an exhaust fan 32, bolts 33, a switch 34, a handle 35, a lower locking buckle 36, and a grounding post 37. The lower box 3 is connected to the middle box 2 by the lower locking buckle 36 and can be completely disassembled for easy product assembly and disassembly. The middle box 2 is connected to the upper box 1 on one side by a hinge and on the other side by the central locking buckle 21. The upper box 1 can be flipped open for easy inspection. The propellant concentration detector readings are checked. Bolts 33 are pre-embedded at the bottom of the lower housing 3, and the fixing bracket 4 is fixed to the lower housing 3 by bolts 33. The middle housing 2 is equipped with a concentration detector and a detector shelf on its side. The shelf is evenly perforated on each side so that the concentration detector probe can fully contact the air inside the packaging box. The concentration detector has an alarm function. When the propellant concentration inside the packaging box exceeds a certain value, an alarm will be triggered. An exhaust fan 32 is installed on one side of the packaging box, and a filter screen 22 is installed on the opposite side to help the air inside the packaging box circulate. The outside of the exhaust fan 32 is connected to the water tank 7 through a hose 6 to deliver the air inside the packaging box to the water tank 7.
